TYPE-WRITING MACHINE.

"SPECIFICATION formingpart of Letters Patent No. 660,231, dated October 23, 1900,;

Application filed January 25, 1900. Serial No. 2,737. (No modal.) T

To atZZ whom it may concern:

Be it known 'that I, FRANZ X. WAGNER, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a full, clear, and exact description.

My invention relates to type-writing machines, and more particularly to mechanism for writing accent-marks with facility.

The object of the invention is to provide a simple and efficient mechanism of the character described and preferably one which is in the nature of an attachment that is adapted to be applied to cooperate with any of the various type-carriers in the machine.

To this end my invention consists in the novel arrangement and combination of parts to be hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a transverse vertical sectional view of a machine embodying my invention, the section being taken centrally through the machine. Fig. 2 is a detail plan view of a portion of the mechanism to be hereinafter described. Fig. 3 is a side view of the same with parts broken away for the purposeot better illustration.

In illustrating my invention I have shown it applied to the well-known Underwood type-writing machine, to which said invention is specially adapted, though obviously the invention may be applied to other typewriting machines, and the necessary changes in detail of construction for the adaptation of the invention to other machines will readily occur-to those skilled in the art to which this invention appertains.

In the drawings, 1 designates the framing of the machine, in which is mounted a segmental plate 2. This plate 2 carries a pivot 3, upon which the type-carriers or type-bars 4 are pivotally mounted. Each of the typecarriers or type-bars 4 is connected to a link 5, pivoted to the framing of the machine, as indicated at 6, and pivotally united to a keylever 7, as indicated at 8. The key-levers 7 are each provided with the usual finger-key 9 and are pivoted to the framing of the machine, as indicated at 10. Each of the type manner.

has an arm 19 secured thereto.

bars or carriers 4 is provided with a nose 11,

' which is adapted to abut against a universal bar 12 in the movement of the type-bar'to the printing-point and to cause a rearward movement to be given to the universal bar.

I The carriage-feed mechanism or escapement is connected to this universal bar, and each complete movementthereof causes the platencarriage 13 to be fed one space in the usual In the present instance this feed mechanism comprises a table 14, which is connected to the universal bar at one end and to the crank-arms 15 at'the other. The table carries a plurality of feed-dogs 16, which successively engage a rack 17, carried by the carriage, so as to effee'ta feed of the carriage at each complete lateral movement of the feed-dogs to and from the initial position. The arms 15, hereinbefore referred to, are rigidly connected to a rock-shaft 18, which This arm 19 is provided with an extension 20, against which a crank-arm 21 is adapted to bear. This crank-arm 21 is fixed upon a rockshaft 22, that is adapted to oscillate in the framing of the machine and to which spacing-levers 23 are connected. These spacing-levers 23 have the usual spacing-key 24 connected to the outer ends thereof. The arm 19, hereinbefore referred to, is provided with a slot 25*,into which a pin 26 projects.

This pin 26 is carried upon a crank-arm 27,

that is rigidly connected to a rock-shaft 28. This rock-shaft 28 is provided with arms 29, 8 to each of which is pivoted a feed-pawl 30, that cooperates with a ratchet-wheel 31. .Each of 'the ratchet-wheels 31 is connected up in a suitable manner to the ribbonespools upon which the ribbon 32 is carried.

So much of the mechanism as has thus far :been described constitutes mechanism of the wellknown Underwood type writing machine, and I will now proceed to describe the mechanism which cooperates therewith to 5 carry out the purposes of this invention;

Upon the framing l of the machine is adapted to be secured a carrier a, which may be secured in place by suitable means,.such

as the screw 12. This carrier a may be se- 1oo' cured to any portion of the framing in the 'machine adjacent to any of the key-levers in the machine. In the present instan'ceI have illustrated this carrier as connected to the framing of the machine immediately in the rear of one of the key-levers. Pivoted to the carrier to is what I term a locking-dog c, as indicated at d. The movement of the locking-dog around its pivot is limited by the under face of the locking-dog abutting against the top 6 of the locking-dog carrier (1. The locking-dog c is normally maintained in the elevated position by a spring f, which in the present instance is located within the dogcarrier (1 and abuts against the lower face of the locking-dog. Projecting through an aperture g in the locking-dog is a rod h, which is adapted to be connected to any of the keylevers which is to constitute what I term a blank key in the machine. 1 term this key a blank key, because in the operation thereof no feed of the carriage is eifected, as will hereinafter more fully appear. Surrounding the rod h is a coiled spring 1', one end of which bears against the upper face of the locking-dog c and the other end of which bears against an adjusting screw or screws j by means of which latter the tension of the spring can be adjusted. In the normal position of the parts (represented in Fig. 1 of the drawings) there is practically no tension exerted by the spring t' upon the locking-dog; but when the blank key is depressed the spring t' is immediately placed under'teusion and is sufficient to overcome the tension of the spring f, so as to depress the locking-dog when it is free to be depressed. The free end of the locking-dog is adapted to cooperate with a locking-abutment it, which looking-abutment is carried upon the rock-shaft 28 and is provided at the upper end thereof with a notch Z. In the normal or unlocked posit-ion (represented in Fig. l of the drawings) the locking-dog is maintained above or out of the path of the locking-abutment by means of the spring f.

Having described a construct-ion embodying my invention, I will now proceed to describe the operation thereof.

A depression of the blank key will first cause the universal bar to be shifted by the contact of the nose 11 of a type-carrier therewith. Motion transmitted in this manner to the universal bar will cause the feed mechanism to be given a lateral movement in the direction of the arrow as, which movement in itself, however, is insufficient to cause the carriage to be fed, it being necessary for the feed mechanism to return to the normal position before a feeding of the carriage is effected. This movement of the feed-dog is transmitted through the arms 15 to the rockshaft 18 and from the rock-shaft 18 to the arm 19, which will cause the rock-shaft 28 to be vibrated, causing the locking-abutment to be moved in the direction of the arrow y a sufficient distance to bring the notch Z beneath the free end of the locking'dog. The depression of the blank key places the locking-dog under the tension of the spring 2', and as sooii as the recess or notch Z is brought into position beneath the locking-dog it will be forced by the spring 5 into the notch, and the nose m of the locking-abutment will contact therewith and will prevent the locking-abutment from returning to the normal position, there by preventing the entire carriage-feed mechanism from resuming the normal position, and consequently preventing a feed of the carriage. It will be observed that this same movement of all parts of the spacing mechanism is effected when the spacing-key 24 is de* pressed. The depression of the spacing-key causes the arm 21 to be elevated, thereby shifting the parts of the carriage-feed mech anism in the manner described by reason of the cooperation of the arm 21 with the ex tension 20. It should be understood at this point that the so-called blank key is provided with the desired accent-m ark and thata depression of the key will cause an imprint of the accent-mark at the printing-point. The positioning of the accent-mark upon its typebar will of course depend upon the character of the mark and the position it is to occupy with relation to the letter to be written. The depression of the blank key having made the imprint of the accentmark upon the paper adjacent to the letter to be written and having automatically locked the carriagefeed mechanism out of operation, the desired letter which is to cooperate with the accentmark is then written. A movement or depression of the writing-key, which causes an imprint of'the letter, will produce a slight movement of the feed mechanism in the direction of the arrow as in the manner hereinbefore described, and this movement will cause the locking-dog to be freed from the nose 'm of the locking-abutment, and the locking-dog will be forced into the elevated position by the spring f, because of the fact that the spring 2' at, this time is not under tension and aifords no resistance to the upward movement of the locking-dog. It will thus be seen that a movement of the blank key causes an imprint of the accent-mark to be made and simultaneously locks the carriage-feed mechanism out of operation and that a depression of any of the writing-keys will cause an imprint to be made in the same space that the accent-mark has been imprinted. At the same time an automatic release of the feed mechanism will be effected, so that the operator may proceed with the Writing in the usual manner. It will likewise be observed that the locking of the feed mechanism out of operation during the imprint of the accent-mark and the character which cooperates therewith and the releasing of the feed mechanism immediately after such character is written is efiected automatically.

While I have described with considerable detail a construction embodying my invention, I am aware that various changes may be made without departing from the spirit of my invention. Thus while I have shown the locking mechanism so constructed as to be operated in part by the mechanism which directly effects the feed of the ribbon, but which is nevertheless controlled and operated by the feeding mechanism, it is obvious that this movement of the parts may be effected from any portion of the carriage-feed mechanism.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
